I suppose that also highlights the use of maximum continuous power rather than full power in high speed cruise or extended climbs.
I discovered that an aircraft with an injected engine may not actually require the manual selection of alternate air when intake icing occurs as this can be automatic. Varying amounts of alternate air can be automatically selected depending on the severity of the blockage.
We can then cross check the EDM with primary instruments and if both agree then it is very quick to realise that there is an actual problem rather than a gauge problem.
Sounds like a useful bit of kit but presumably it must have duplicate probes to do this?
